I wouldn't agree that Portland is less bike-friendly than Amsterdam or Copenhagen. There aren't any logistical problems involved in biking throughout the majority of the city (deep southwest and the "hundreds" are a bit iffy) while avoiding busy streets. Not as many people happen to take advantage of Portland's bike-friendliness as in Amsterdam or Copenhagen, but I suspect that this is because the cost of driving -- in terms of both time and money -- is significantly higher in Europe.
Portland doesn't need to become like Amsterdam. A low-speed street is just as good as a cycletrack. Aside from a couple of bridge crossings and maybe the extension of the Esplanade up to St. Johns, I don't see that many improvements are necessary. There are a few streets that bikes commonly use that could stand to be repaved. The outer eastside would be more bike-friendly if the side streets were actually all paved, instead of turning into mud pits whenever it rains.
